1794-ACN15 | Allen Bradley Flex I/O ControlNet Adapter

Product Overview

The Allen Bradley 1794-ACN15 functions as a high-performance communication interface within the Flex I/O system. This 100% brand new ControlNet adapter bridges the gap between the ControlNet network and up to eight Flex I/O modules. It manages data exchange and provides the necessary power to the backplane, ensuring seamless integration of field signals into your broader control architecture.

FAQs

• Does this unit come in original packaging?

  Yes, we provide only 100% brand new and original Allen Bradley hardware in factory-sealed packaging.

• How do I set the network address for the 1794-ACN15?

  Use the two rotary switches located on the front of the module to select the unique ControlNet node number (01-99) before powering the system.

• What is the maximum number of I/O modules this adapter can manage?

  A single 1794-ACN15 adapter supports a maximum of 8 Flex I/O modules connected via the backplane.

• Does the adapter provide power to the attached I/O modules?

  The adapter converts the 24V DC input into 640 mA of 5V DC backplane power to drive the internal logic of the connected modules.
